A validation check is a procedure that ensures the data entered into a computer is correct and sensible. It is often used in computer programming and is designed to catch mistakes and errors. This can be done through various methods such as data type checks, range checks, or format checks.

Here's a step-by-step explanation:

1. A validation check is a process or function that is used in computer programming.
2. Its main purpose is to ensure that the data entered into a system is correct, sensible, and usable.
3. It works by checking the data against certain conditions or criteria. These conditions could be a specific data type, a certain range of numbers, a particular format, etc.
4. If the data does not meet these conditions, the validation check will flag it as an error. This helps to prevent mistakes and inaccuracies in the data.
5. Therefore, a validation check is a crucial tool in maintaining the integrity and accuracy of data in a system.
